We've had a few keen devs get their hands on our Arduino IoT starter kit: https://dev.telstra.com/iot-marketplace/arduino-mkr-nb-1500
These kits come with a free trial Cat-M1 (LTE-M) SIM card (details in a previous forum post). They are not capable of NB-IoT by default.
The u-blox SARA-R410M-02B embedded IoT module and Arduino board itself ARE compatible for NB-IoT, however they have been officially Telstra certified with this device for Cat-M1 only, so we only provide Cat-M1 as default. The public list of the M2M modules that have been certified to work on Telstra’s network can be found at https://www.telstra.com.au/content/dam/shared-component-assets/tecom/iot/capabilities/certified-devices/telstra-m2m-certified-devices-modules.pdf
If your use case specifically requires NB-IoT connectivity rather than Cat-M1 (see our FAQs for the comparison, or this whitepaper for further details of the 2 different technologies), please contact TelstraDev and we can work to enable Nb-IoT. This will require a re-configuration of your SIM, changing the Radio Access Technology (RAT) of the device, and a possible firmware upgrade to the ublox module. Please keep in mind Cat-M1 is the preferred technology because of its certification.
We also ask that all developments with our network comply with the Wireless Application Developers Guidelines for IoT and Our Customer Terms which can be found online here https://www.telstra.com.au/content/dam/tcom/personal/consumer-advice/pdf/business-b/dataservices-m2m.pdf
Does your use case require NB-IoT specifically? We'd love to hear from you! Please leave a note below or email us: firstname.lastname@example.org
